Steam doesn't issue a VAC ban based on player reports, so that's irrelevant. You got banned because VAC detected you using a cheat. This thread is going to be closed by a moderator. So before that happens I'll tell you that if you believe you were wrongfully banned, the only thing you can do is contact support, as nobody on these forums can help you. All VAC bans are permanent, and for more information regarding a VAC ban go to this thread: http://steamcommunity.com/discussions/forum/9/882959527688934488/

As already said if you believe you were wrongfully banned then contact support, nobody here can help you. As a side note VAC detected a cheat used on your account and promptly issued you a ban, it doesn't matter if it was you or not using the account at the time it was detected as the account security is your responsibility.
